About this network
A US Department of Defense network from the block DNIC-ASBLK-05120-05376, registered to the DoD Network Information Center (DNIC).
What it's used for
- US government / military networking, at some scale: it originates dozens of prefixes, drawn largely from the DoD's 214.0.0.0/8 plus blocks named for the Defense Information Systems Agency (DISA) computing services directorate.
Notable
- A government / military network, not a commercial ISP or host.
- The DISA-named blocks suggest shared, agency-run computing infrastructure serving other DoD components, rather than a single base network.
- The DNIC registration itself names no specific base or unit; the DISA attribution comes from the names on the address blocks it announces.
Interesting
- DISA is effectively the Department of Defense's internal IT and telecommunications provider, running the networks and data centres that other military organisations consume as a service.
